Operando chemo-mechanical evolution in LiNi0.8Co0.1Mn0.1O2 cathodes

{{output}}
Ni-rich LiNi x Co y Mn z O2 (NCMxyz, x + y + z = 1, x ≥ 0.8) layered oxide materials are considered the main cathode materials for high-energy-density Li-ion batteries. However, the endless cracking of polycrystalline NCM materials caused by stress accelerate... ...
